水分对颗粒煤瓦斯扩散系数的影响规律研究

Study on the Influence Law of Moisture on the Diffusion Coefficient of Particulate Coal Gas

本文以煤层注水为背景,研究高变质程度的颗粒煤在相同注气量的条件下瓦斯扩散系数随水分含量增加的变化规律,并分析水分对煤体瓦斯扩散系数的影响机理。

Based on the coal seam water injection,this paper studies the variation law of gas diffusion coefficient with the increase of water content under the same gas injection condition,and analyzes the influence mechanism of water on coal gas diffusion coefficient.
